LOUIS W. FRANE, OF COLBY, WISCONSIN.

BOWER-TRANSMISSION ATTACHMENT FOR MOTOR-VEHICLES.

To all whomit may concern:

Be it known that 1, Louis W. FRANE, a

citizen of the United States, residing at Colby, in the county of Clark and State of iscon'sim' have invented new and useful improvements in Power-Transmission Attachments for Motor-Vehicles, of which the following --is a specification.

This invention relates to power transmission attachments for motor vehicles, the object of the invention being to produce a power transmission unit adapted to be easily and quickly attached to and disconnected from the front of a motor vehicle, the atthe engine tachment enabling the power of of the motor vehicle to beutilized for all ordinary farm power purposes. The improved attachment is designed to take the ."place of thereon the ordinary farmstationariy engine now in common use and will be ound more efiective and reliable than such sta- 'tiqnary enginefor the reason that it will give a steadier pull when load is imposed due to theinumber of cylinders of as motor vehicle engine as compared. with .1 the stationary engine which usually has but a single cylinder.

With the above and other objects in view, the invention consists in the novel construction, combination and arrangement of parts, herein fully described, illustrated and claimed. v

In the accompanying drawin s:, Figure 1 is a plan view partly in section showing the power transmission attachment in its applied relation thereto.

Fig. 2 is a perspective view, of the power transmission attachment detached.

means of brackets 2 on'the front endof a motor vehicle, the brackets being permanently connected to the frame 1 and detach ably connected to theframe of the motor vehicle by fastening means 3. a

The frame is provided with bearings 4: for a shaft 5' having at. one end a clutch mem- Speciflcation of Letters Patent. @atented sfipt. 3, 1918..

Q ber 6 which is designed to engage a corre sponding clutch member 7 on the front end of the shaft 8 of the motor vehicle engine conventionally represented at 9. The shaft 5 has faston the end thereof farthest from the motor vehicle a belt pulley 10 from which thepower is delivered to any suitable machine. The shaft 5 also has'fastthereon a smaller belt pulley ll'from which a driving belt extends around another pulley 12 on the shaft 13 of a fan which is positioned directly in front of the radiator of the motor vehicle to provide an additional amount of air for cooling the radiator and engine, I

it being well known that an engine heats more rapidly when the vehicle is standing still. Another belt extends from the shaft 5 around a puller 15 on a governor driving shaft 16;the sha t 16 being geared to a vertical governor shaft 17 by gears 18. 19 represents a centrifugal governor actuated by the shaft 17 and operatively connected with a bell crank lever 20 from which a rod 21 extends rearwardly to the carbureter 22 of the engine. The connection 21 operates on the throttle valve of the carburetor to automatically cut down the supply of gas when only a light load is imposed onthe engine,

preventing the engine from racing and thereby wasting fuel. On the other hand when a load is imposed on the engine, the

1 connection 21 operates to open the throttle Valve and furnish the additional mixture to the engine required'by such load. Thus the operation of the powentransmission attaehment is automatic and is governed by the load imposed on the engine. The device. as a whole may be easily and quickly attached to the motor vehicle and coupled to the engine shaft and ,fthecarbureter. When the motor vehicle being used for ordinary.

purposes, it gives no evidence ofanything additional to the ordinary. equipment, no alteration of the vehicle belng requiredin order to adapt it to be used in connection with the power transmission attachment herein described and shown.

A power transmission attachment for mo-' tor-vehicles, comprising a frame, means for detachably fastening said frame to the v frame of a motor vehicle, a shaft journalcd in bearings on the frame of the attachment, means on said shaft for coupling the same to the engine shaft, :1 power delivering belt nlley on the shaft of the attachment, a fan journaled on the attachment frame and driven by a belt from the attachment shaft, 5 a. governor supported by the attachment frame and driven by a belt from the attachment shaft, a. bell crank lever operativcly connected with a moving part of said govcruel, and a connection between said bell crank lever and the throttle valve of the 10 carburetor of the motor vehicle engine.

In testimony whereof I affix my signature.
